AWS CLI Command Reference

[ aws . elb ]

create-load-balancer

Description

Creates a Classic Load Balancer.

You can add listeners, security groups, subnets, and tags when you create your load balancer, or you can add them later using CreateLoadBalancerListeners , ApplySecurityGroupsToLoadBalancer , AttachLoadBalancerToSubnets , and AddTags .

To describe your current load balancers, see DescribeLoadBalancers . When you are finished with a load balancer, you can delete it using DeleteLoadBalancer .

You can create up to 20 load balancers per region per account. You can request an increase for the number of load balancers for your account. For more information, see Limits for Your Classic Load Balancer in the Classic Load Balancers Guide .

Options

--load-balancer-name (string)

The name of the load balancer.

This name must be unique within your set of load balancers for the region, must have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and cannot begin or end with a hyphen.

--listeners (list)

The listeners.

For more information, see Listeners for Your Classic Load Balancer in the Classic Load Balancers Guide .

(structure)

Information about a listener.

For information about the protocols and the ports supported by Elastic Load Balancing, see Listeners for Your Classic Load Balancer in the Classic Load Balancers Guide .

Protocol -> (string)

The load balancer transport protocol to use for routing: HTTP, HTTPS, TCP, or SSL.

LoadBalancerPort -> (integer)

The port on which the load balancer is listening. On EC2-VPC, you can specify any port from the range 1-65535. On EC2-Classic, you can specify any port from the following list: 25, 80, 443, 465, 587, 1024-65535.

InstanceProtocol -> (string)

The protocol to use for routing traffic to instances: HTTP, HTTPS, TCP, or SSL.

If the front-end protocol is TCP or SSL, the back-end protocol must be TCP or SSL. If the front-end protocol is HTTP or HTTPS, the back-end protocol must be HTTP or HTTPS.

If there is another listener with the same InstancePort whose InstanceProtocol is secure, (HTTPS or SSL), the listener’s InstanceProtocol must also be secure.

If there is another listener with the same InstancePort whose InstanceProtocol is HTTP or TCP, the listener’s InstanceProtocol must be HTTP or TCP.

InstancePort -> (integer)

The port on which the instance is listening.

SSLCertificateId -> (string)

The Amazon Resource Name (ARN) of the server certificate.

Shorthand Syntax:

Protocol=string,LoadBalancerPort=integer,InstanceProtocol=string,InstancePort=integer,SSLCertificateId=string ...

JSON Syntax:

[
  {
    "Protocol": "string",
    "LoadBalancerPort": integer,
    "InstanceProtocol": "string",
    "InstancePort": integer,
    "SSLCertificateId": "string"
  }
  ...
]

--availability-zones (list)

One or more Availability Zones from the same region as the load balancer.

You must specify at least one Availability Zone.

You can add more Availability Zones after you create the load balancer using EnableAvailabilityZonesForLoadBalancer .

(string)

Syntax:

"string" "string" ...

--subnets (list)

The IDs of the subnets in your VPC to attach to the load balancer. Specify one subnet per Availability Zone specified in AvailabilityZones .

(string)

Syntax:

"string" "string" ...

--security-groups (list)

The IDs of the security groups to assign to the load balancer.

(string)

Syntax:

"string" "string" ...

--scheme (string)

The type of a load balancer. Valid only for load balancers in a VPC.

By default, Elastic Load Balancing creates an Internet-facing load balancer with a DNS name that resolves to public IP addresses. For more information about Internet-facing and Internal load balancers, see Load Balancer Scheme in the Elastic Load Balancing User Guide .

Specify internal to create a load balancer with a DNS name that resolves to private IP addresses.

--tags (list)

A list of tags to assign to the load balancer.

For more information about tagging your load balancer, see Tag Your Classic Load Balancer in the Classic Load Balancers Guide .

(structure)

Information about a tag.

Key -> (string)

The key of the tag.

Value -> (string)

The value of the tag.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
